A Rapid Low-Temperature Synthetic Method Leading to Large-Scale Carboxyl Graphene Original Research Article Chemical Engineering Journal, Available online 30 October 2013, Pages Ning Pan, Debin Guan, Yuntao Yang, Zhenling Huang, Ruibing Wang, Yongdong Jin, Chuanqin Xia
Graphical abstractCarboxyl graphene was prepared by selective reduction of the epoxy and carbonyl groups on graphene oxide using thiourea dioxide, while carboxyl groups were left behind. The carboxyl graphene possessing relatively high surface area still contains approximately 6.9 ± 1.6 mmol of carboxyl groups per gram of material. The method is feasible for scale-up.
